-Utilities for representing genomic loci and reference-genomes.
+Utilities for working with genomic loci.
 
-Contains three packages:
-- [`loci`](src/main/scala/org/hammerlab/loci)
-- [`reference`](src/main/scala/org/hammerlab/reference)
-- [`strings`](src/main/scala/org/hammerlab/strings) 
+- [`parsing`](src/main/scala/org/hammerlab/genomics/loci/parsing): utilities for parsing string-representations of loci. 
+- [`set`](src/main/scala/org/hammerlab/genomics/loci/set): `LociSet` data-structure: stores genomic-loci ranges and allows for intersection/containment checks.
+- [`map`](src/main/scala/org/hammerlab/genomics/loci/map): `LociMap` data-structure: allows for mapping genomic ranges to arbitrary values.
+- [`iterator`](src/main/scala/org/hammerlab/genomics/loci/iterator): iterators for traversing genomic loci.
